Think of your badge buddy as a more simplistic and convenient way to identify the roles of medical personnel such as doctors and registered nurses. In some cases they are used to easily indicate and identify entire departments like Emergency Room, Security, Pharmacy, etc. The badge buddy can provide a quick means of knowing who is associated with which vocation simply by seeing the color code you choose.
Additionally, the badge buddy is also a fantastic way to see who is a visitor, volunteer, medical student, or intern, simply at a glance. Seeing who is in their designated area for security purposes and who can help in case of an emergency has never been so easy.
